I would just kill Lois, period. Move Clark to a more suburban area of Metropolis, and have him concentrate on being a novelist. No kids. No wife. And fuck the whole "reporter" schtick (sp?). Have him date women, like a single guy does. Have his research for books or freelance articles for the Planet be his motivation into dealing with true political and social corruption. Gets him back to his Golden Age roots, but, still allows him a whole new lease on life. Also, kill Lex Luthor, and create someone new to fill the void of "archnemesis". I've always preferred someone like Zod, anyway...
